Ukraine conflict: Ukraine to receive additional air-defence radars

Ukraine will receive additional Hensoldt TRML-4D active electronically scanned array (AESA) radars to strengthen its air defences.

Under the agreement, Hensoldt will supply six systems to Ukraine for EUR100 million (USD108.2 million), the company announced on 16 May.

The radars will be delivered in the second half of 2023, after adequate training has been provided.

In 2022, the company delivered four TRML-4D radars for Ukraine's Diehl Defence IRIS-T surface-launched medium-range (SLM) air-defence systems. In January 2023, two additional TRML-4D radars were ordered, although these systems were not intended for the IRIS-T SLM system, Janes understands.

This latest order, funded by the German government, is similarly not intended for the IRIS-T SLM system, a Hensoldt spokesperson told Janes.

The TRML-4D is a software-defined C-band (4–8 GHz) AESA radar that utilises a gallium nitride (GaN) solid-state transmitter. The system can detect close to 1,500 targets in a 250 km radius to a height of 30 km and is capable of detecting platforms with a radar cross-section of 0.01 m². Fighter aircraft can be tracked as confirmed targets at ranges of more than 120 km and supersonic missiles from more than 60 km. It can automatically trigger electronic counter-countermeasures and allows locally developed solutions to be integrated into the radar's operations suite.
